As the country’s largest solar market, California stands to lose the most from the 30 percent tariff, with an expected 1,079-megawatt decline in new solar capacity between 2018 and 2022. California is trailed by Texas and Florida, which are expected to lose 674 megawatts and 513 megawatts, respectively.

Nationally, the GTM Research analysis shows that utility-scale solar will bear the brunt of the losses, accounting for 65 percent of the anticipated decline.
